httpwerequest
httpwerequest 可不可这样使用比如说我用httpwerequest GET方式打开了一个界面，
再从所得的文件中提取了一些信息。就直接将提交方式改成post进行数据提交。
会报错。请大侠们帮帮忙啊。。。。。
try
{
CookieContainer cc = new CookieContainer();
string _post = txt_paraments.Text.Trim();
string _url = txt_url.Text.Trim();
HttpWebRequest request;
////登陆
request = (HttpWebRequest)WebRequest.Create(_url);//实例化web访问类
request.Method = "POST";//数据提交方式为POST
//模拟头
request.ContentType = "application/x-www-form-urlencoded";
byte[] postdatabytes = Encoding.UTF8.GetBytes(_post);
request.ContentLength = postdatabytes.Length;
request.AllowAutoRedirect = false;
request.CookieContainer = cc;
request.KeepAlive = true;
//提交请求
Stream stream;
stream = request.GetRequestStream();
stream.Write(postdatabytes, 0, postdatabytes.Length);
stream.Close();

HttpWebResponse response = (HttpWebResponse)request.GetResponse();
////保存返回cookie
